ESR is only supported for a year. It allows for 2 months in between versions before one version is dropped.

IE is going the same route with annual updates. IE 10 is an exception due to the incompetence of the Windows 8 team forcing WDDM 1.2 and DirectX 11.1 onto it which requires significant backporting.

So this time next year IE 11 will be out or in RC states and the following IE 12 etc. Organizations need to learn to adapt to change more rapidly. It is not like a minor release is anything like the huge rewrite of apps that resulted from IE 6 to IE 7 or even 8. Your browser should always be updated at a regular basis.

Additionally, any site that renders text will look better. Firefox 17 doesn't render text at the higher DPI supported by new MacBook Pros, causing every site to look blurrier than it would in Chrome or Safari.

For the record, the same is true in Windows: change the scaling factor of the OS, and Firefox simply scales the same low-res text. It's unclear whether the change I mentioned in nightlies will fix Windows as well; I simply haven't tried it yet.

To enable click-to-play for all plugins go to about:config in the location bar and set “plugins.click_to_play” to true.The feature is considered still under development which is why it's not enabled by default.
